Be it known that I, OLIVE K. WooLLEN, a citizen of the -United States, residingat. Franklin, in the county of Johnson and State oflndiana, have invented certain new and useful Improvements in Invalids Beds, `of.v

which the following is a specification. Y

This invention relates to beds for invalids;

and the object of the invention is. to .provide a bed of the above character which is capable of beinlr swung so as Ato chan e the p ositlon of the patlents without disturbing them..

vA further objeot'of the invention is to pro- 'vide an invalids bed with a central aperture which is normally closed by a movably mounted stand which may be raised or lowered by means of a screw shaft in order that the patientsmay be provided and. have access to the necessary vessels without subjecting the patients to unnecessary handling or' slnfting.- v

A further object of the invention is to rovide an invalid's bed which is arrange so that the head or feet of the patients may be raised into lan inclining positlon.

I accomplish the objects of my invention by means of a bed illustrated in the`accompanying drawings, forming a part hereof, in whic Figure 1 is a top' or plan view of an invalidsbed embodylng my said invention, in which a ortion of the mattress 'is broken away to isclose the parts underneath. Fig. 2 is a side elevation of the construction .shown in Fig. 1, except that the mattress has been omitted. Fig. 3 is a rear elevation of the bed. Fiig. 4 1s ya central vertical sectional view o a portion of the bed showing the movable stand or table occupylng its normal position. Fig. 5 is a perspective detail.

In the drawings, 1 represents the head and 2 the foot ofthe bed, each of which rest upon the bases 4 and 5. The bases are held in normal relation with one another by means of a plurality of connecting bars 6.

The bed proper consists of a rectangular frame comprising the end rails 7 and 8 which are secure at each end by the side rails 10, the latter being secured to the end rails bymeans of any suitable fastening employed in the art of bed construction.. and 8, and the side rails'lO support an inner frame which carries the woven wire springs. This inner frame is divided into the forward member 13 and the rear member 14 which are hingedly secured to the stationary mem`- The end rails 7 I ber-s `12 oftheiframe by means of the hinges 16. This arrangement vadmits fofv these end V,1nrnr1b`ers` `being raised into an inclineposition, as shown in Fig. 2.. -The members 13 andf 14 are held in elevated vposition by means ofthe bracesf17 whichv are pivotally secured lto said 'members and engage notches 18 inthe side rails 10. The Inembers 13 and v14 of the inner frame are notched at 20 so that the braces 17 may be nested when said members are in their reclining or normal position. To add an additional support and thus prevent the woven wire springs from sagging, I'provide the coil-springs 25 which bear against the under side of the Woven Wire springs while the lower ends of said springs are mounted u on the rails 26 4which are' supported by the Is1de rails 10. The bed provided with the usual mattress 28 which hes vupon the woven wire springs and is held in position by means of the hooks 29, which are common to folding beds. The Woven wire springs and the mattress 28 are each provided with a central registermg a erture 30. o osed by means ofthe cushion 31 whlch 1s formed of vsimilar material as the mattress 28. The cushion 31 is mounted on the springs 34 so that it will move with the mattress 28 when the weight of the patlent 1s thereon. The springs 34 are mounted on the. base-plate 35, which base-plate rests on the head-plate 36, the latter belng secured t0 the vertical screw shaft'37. The shaft 37 passes 'through the screw threaded collar 38, and by meansof'the hand wheel 39, the headplate 36 together with the cushion 31 may be raised or lowered. -The base-plate 35, carrying the cushion 31, is prevented from .moving laterally off of the head-plate 36 by means of the hook-shaped springs 42 which are secured at diametrically opposite sldes of the head-plate 36 and are susceptlble of being bent away from said head-plate and thus permitting the base 35 to be removed.

This aperture is normally The screw-shaft 37 is moved into its extreme collar 38 is secured to the floor 45 which is' suspended from the bottom of the bed by means of the uprights or hangers 46. y

The bed proper may be swung so as to be able to change the position of the patlent by attaching to the under side of the end rails 7 and 8 the `semi-circularly Vformed supports the pin 72 (see Flgp3) which W of the hea 56, which rest and su port'the bed at all A sleeve 60 surrounds the bolt 58 and ex-4 tends from the bar 55 to the rocker 50` so as to compensate for the thickness ,of the osts of the head 1. The bars are secure together at their top ends by means of the bolt 62. In order to s'ecurelyhold the bed when tilted into an angle I rovide the clamping bolt which ,passes t rough both the bars 55 and 56 and throu h a slot 66 in the tie rail 67 of the head 1. i he slot 66 is cut onan arc which is concentric with the pivot bolt 51, and the vertical bars 55 and 56 are clamped tightly against the surfaces of the tie rail 67 by means of the hand wheel 70 mounted on the threaded end of the clampin bolt 65. The hand wheel 70 is preferab y placed on the back side of the head 1 of the bed, where it will be easily accessible and still be hidden from View. As an additional security for holdin the bed when it occupies its normal vertica position I may rovide ass throu h one ofthe tie rails of the head 1 and into t e end rail 7 of the bed. This pin is not deemed absolutely necessary, but may be added if desired.

Having thus fully described my said invention, what I desireto secure by Letters Patent, is-

1. An invalids bed comprising 4a head and foot member secured together and each of said members being provided with a projecting base, a bed-frame arranged between the head and foot members, means for pivotally mounting said bed-frame between the head and foot members, semi-circularly formed supports secured to the underside of the bedframe and adapted to ride upon the projecting portions of the bases, means for changing the position of the bed-frame, and means for locking the bed-frame in the desired position.

2. An invalids bed comprising a headY and foot member secured together, each of said members being provided with a projecting base, a bed-frame arranged between the head and foot members, means for pivotally mounting said bed-frame between the head and' foot lmembers, semicircularly formed supports secured to the underside of thebed-frame and adapted to ride upon the projecting changing t woven-wire sprlng supporting frame comprising a plurality of sections in which the middle sections are adapted to normally lie in a horizontal position while the end sections are susceptibleof` being moved into an inclined position, means for hingedly securportions cuiA the bases, means for .ing the ,end sections to the middle sections,

means for holding the end sections when raised, and means for locking said bed-frame in a desired position. f

` 3. An invalids bed comprising a head and foot member secured toget r, each member being provided with a projecting base, a bedframe arranged between the head and.Y foot members, means for ivotally mounting said bed-frame between t eV head and foot members, semi-circularl formed supports secured to the underslde of the bed-frame and adapted to ride upon the pro'ecting portionsl of the bases, means for c anging the e position of .the bed-frame, a

position of the bed-frame, a Woven-wire' spring provided with a centrally located aperture and its supporting frame comprising a plurality of sections in which the mlddlesections are adapted to normally lie in a horizontal position 'while the end sections are susceptible of being moved into an inclined position, means for hingedly securing the end sections to the middle sections, means for.

holdin said 4end sectionsk when raised, a head-p ate adapted to register with the central aperture 1n the woven-wire springs, means for changin the position of said headplate, and means` or locking said bed-frame in a desired position.

4. An invalid s bed comprising a head and foot member, each of said members being provided with a projecting base, a bed-frame arranged between the head and foot members, means for pivotally mounting said frame between the head and foot members, semi-circularly formed supports secured to the underside of the bed-frame and ada ted to ride upon the projecting portions o the bases,.a plurality of u ri hts secured to and ada ted to move wit t e bed-frame, said u rights straddling the head member, and a c amping device passing through the u rights and the head member,'for locking tllie bed-frame in the desired osition.

In witness whereof, I, ave hereunto set my hand and seal at Indianapolis, Indiana, this 14th day of August, A. D. one thousand nine hundred and seven.
